✨ COMEDI_DISCONNECT_RO(3) ✨

okay bestie, welcome to the Comedi reference — this page is COMEDI_DISCONNECT_RO(3), and we’re about to disconnect a route like it’s an ex you don’t text back. 💅

💖 NAME 💖

comedi_disconnect_route — disconnect device-global route

🦋 SYNOPSIS 🦋

#include <comedilib.h>

int comedi_disconnect_route(comedi_t * device, unsigned int source,
                            unsigned int destination);

🌸 STATUS 🌸

status check: this function is alpha. she’s iconic but still in her experimental era, bestie. 🧚

🔥 DESCRIPTION 🔥

So this function disconnects a globally-named route if such is connected. That’s the whole vibe. ✨

This operation is effectively the same as calling comedi_set_routing and comedi_dio_config on the appropriate subdevice. No cap.

There are several routes that are not globally dis-connectable via comedi_connect_route, such as (NI_PFI(i) --> NI_AO_SampleClock) as they must be connected via a trigger argument, such as comedi_cmd->start_arg for NI_AO_StartTrigger. Like, those ones have to go through the trigger side door, iykyk. 🚪💫

The source parameter specifies the source of the signal route, whereas the destination parameter specifies the destination. Possible values for source and destination are driver dependent but are generally required to be values that are recognizable globally for a particular device, independent of sub-device. So yeah — driver dependent, but usually they gotta be globally recognizable for that device, not tied to one little sub-device. 🎀

💜 RETURN VALUE 💜

0 on success, -1 on error. That’s it. Clean, simple, main character energy. 😌
